I've owned several PJ's an just ordered a Load Trail. I was told that two brothers own both. If you look at the options you'll see they're identical. One thing I did notice is that some things come as standard features on the load trail where as they're options on the PJ. It is of course built into the LT price. PJ was also a longer lead time on paint options. I'm in the Northeast so lead time for a custom trailer was an issue for me. LT lead time was 4 weeks PJ's was almost double. The fit and finish of the PJ's I owned was very good, I did replace tires on my PJ dump but mostly due to dry rotting issues.
The downside of most trailers is the wiring and paint. PJ and LT both powdercoat but LT was available in standard paint. I opted for the powdercoat, and the LED lighting.
